eero Pro 7 - 6GHz Backhaul instability & Ethernet 1Gbps negotiation bug

Hi everyone, I’m reaching out to see if others are experiencing the same frustrating behavior with the eero Pro 7 (2-node setup). Despite having a solid infrastructure and great signal metrics, the system seems to be fighting against its own hardware capabilities. The Setup: Gateway: eero Pro 7 connected to a 2.5Gbps ONT (Vodafone Italy). Leaf Node: eero Pro 7 in the office via wireless backhaul. Client: PC connected via Ethernet to the office leaf node. Signal: WiFi Analyzer shows a consistent -55 dBm to -45 dBm on the 6GHz band (CH 69) between nodes. The Issues: 6GHz Backhaul "Surrender": After a reboot, the backhaul correctly hits the 6GHz band, and I get the full 2.3Gbps throughput. However, after about 5-10 minutes, the system permanently downgrades the backhaul to 5GHz and stays there. Speed drops to ~1Gbps. Support claims it's for "stability," but with a -55 dBm signal, there is no technical reason to drop the 6GHz link. The system simply "gives up" on the 6GHz radio and never tries to re-evaluate or switch back. Ethernet Negotiation Bug: Frequently after a reboot, the Gateway WAN port negotiates at 1Gbps instead of 2.5Gbps with the ONT. I often have to physically reseat the cable or reboot multiple times just to get the 2.5Gbps link back. It feels like a software handshake issue during the boot sequence. Conclusion: It seems the current v7.x firmware is far too conservative. It sacrifices 50% of the hardware's potential for a "stability" that isn't even at risk given the actual signal strength (-55 dBm). Has anyone found a way to make the 6GHz backhaul more "sticky" or encountered this specific 1Gbps WAN negotiation bug? Thanks!
